Mexico City, May 20 (teleSUR-RHC) The head of the human rights division of the federal attorney general's office in Mexico resigned unexpectedly on Monday.

Eliana Garcia Laguna’s resignation comes only three months after Jesus Murillo Karam was ousted as head of the attorney general's office, known as the PGR, and a year after Garcia's predecessor also resigned from the position.

The credibility of the Mexican government and the country’s attorney general has been severely weakened, especially human rights.

Mexico is currently facing a serious human rights crisis, as the government’s military efforts against organized crime in the country has resulted in a general lack of security in many parts of the country as cartels vie for territory.

Arely Gomez Gonzalez, who replaced Murillo in February, said that human rights would be a top concern under her watch.

According to El Pais, Garcia counted on the support from human rights groups in the country. Her departure is set to further undermine the PGR's credibility. The Mexican security forces have also been under increased scrutiny, having been implicated in a number of massacres. Most notably local police are accused of having been involved in the forced disappearance of 43 students from the Ayotzinapa teachers' training college.

The world's attention fell on Mexico as millions marched demanding their safe return and called for those responsible to be held accountable.

The 43 forcibly disappeared students is not an isolated case. State security forces are also accused of participating in massacres in the cities of Tlatlaya and Apatzingan.
